Introduction
The IM-X40 control unit (referred to as the control unit in this document) is an intelligent terminal for the point of sale (POS) environment. The control unit offers the following features:
A fast SL enhanced Intel® i486™SX2 processor gives you the power and speed you need to process your transactions.
Because the TM printer fits on top of the control unit, you can install it in a small area, giving you more counter space.
The PC-based, open-architecture control unit contains one standard 16-bit ISA expansion slot and a second expansion slot for a PCMCIA expansion module, allowing you to expand your system.
Using a standard SIMM, you can install up to 32MB of memory in a control unit.
The built-in IBM® PS/2® keyboard port can support a variety of PC/AT® compatible keyboards, so you can select the best one for your environment.
Four serial ports and a combined parallel/optical coupled interface adapter (OCIA) port allow you to connect several industry-standard peripherals to meet your specific transaction processing needs.
The built-in DM display port allows you to install an EPSON® DM-D102 or DM-D203 customer display without requiring you to use one of the additional serial ports.
The built-in VGA port allows you to connect a standard VGA or SVGA monitor directly to the control unit.
Introduction 1
A Nickel-Cadmium (Ni-Cd) battery is available as a option. In the event of a power failure, the Ni-Cd battery backup gives you time (about a minute) to save your current transaction before the control unit shuts down.
Several levels of security keep your critical data safe. The front panel locks, ensuring controlled access to the floppy disk drive and making the removal of the IM module impossible. Multiple levels of passwords keep your system, your data, and your cash drawer secure.
Sophisticated power management functions ensure that you use only the power you need to process your transactions.
The hard disk drive is easy to remove and reinstall. If a system fails, you can be using your same data on a different control unit almost immediately.
The easy-to-update flash ROM has 112KB available for a userdefined program, while 144KB is used by the system.
The BIOS is PC/AT compatible—this means you can run all your favorite PC programs as well as your application-specific software.
Built-in device diagnostics make troubleshooting fast and easy.

Handling Guidelines
Observe these guidelines when handling the control unit:
Make sure you read the safety instructions for the power supply before you attach or remove it.
Never plug a telephone line into the DM display port.
Make sure you always set a password for accessing the drawer kickout test in the device diagnostics utility. The drawer kickout test checks if the cash drawer opens correctly. However, anyone can access the test if you do not define a password.
Make sure you charge the batteries (Ni-Cd* and Lithium batteries) in the control unit. These rechargeable batteries are not charged fully at the factory. (*Ni-Cd battery is an option.)
Do not block any slots or openings on the control unit. These are provided for the ventilation necessary to ensure reliable operation and protection from overheating.
Make sure that any device connected to the AC outlet of the power supply does not consume more than 150 VA.
Make sure that the total power requirements of all the devices getting their power from the control unit do not exceed the control unit power limitations.
When you transport the control unit in its shipping container, make sure you replace the transportation screw.
Make sure you lock the IM module to the lower plastic housing using the lock on the front panel. The module could fall from the housing if it isn’t secured.
Never hold the control unit by the back cover. This cover cannot support the weight of the unit, so it may fall onto the floor.
4 Introduction
You see the following label on the back panel of the control unit:
This connector
cannot be used.
Do not remove this label.
Option
PCMCIA expansion module
This expansion module supports two Type I or Type II PC cards or one Type III PC card.
Ni-Cd battery
The rechargeable Ni-Cd battery supplies power to the control unit for approximately one minute in the event of a power failure. This allows you to save your current transaction before the control unit shuts down.
A 3.5-inch floppy disk drive, 2.5-inch hard disk drives, and SIMMs are also available for the control unit.

Removing the Cover
You need to remove the cover on the IM module to install drives or other internal components or to change jumper settings.
Caution
Components on the internal boards can get hot. After you turn off the control unit, wait at least 10 minutes for the component to cool before you remove the IM module cover.
Follow these steps:
1. Remove the external I/O board, as described above.
Installation 1-9
2.Use a Phillips screwdriver to remove the two additional screws on the top of the cover that secure it to the control unit. Also remove the two screws that secure the cover to the sides of the chassis.
3.Lift the cover straight up, until it clears the chassis, as shown below.
4.Set the cover aside.
5.Ground yourself to the IM module by touching a grounded metal surface.
Caution
Be sure to ground yourself by touching a grounded metal surface every time you remove the cover. If you are not properly grounded, you could generate an electrical shock that could damage a component when you touch it.
1-10 Installation
When you are ready to replace the cover, align the cover over the IM module and guide it straight down. Secure the cover with two screws on top and two screws in the side of the chassis. (Three additional screws secure the external I/O board to the cover and the chassis.)

|
|
3-pin jumper |
|
|
For two-pin jumpers, the jumper is either on (it connects the two pins) or off (it doesn’t connect the two pins).
For three-pin jumpers, the jumper setting is 1-2 when the jumper connects pins 1 and 2. The setting is 2-3 when pins 2 and 3 are connected. You see a 1 and a 3 printed on the circuit board to identify these pins.
To move a jumper from one position to another, use needle-nose pliers or tweezers to pull it off the pins and move it to the desired position.
Caution
Be careful not to bend the jumper pins or damage any components on the board.
1-12 Installation
System board jumper settings
The system board contains three sets of jumpers. Two jumpers control the voltages for the SIMM and COM2. A third jumper controls bank configurations for the SIMM.
The diagram below shows the location of the jumpers on the system board.
